Prior to this change spv_ptrcast (and OpBitcast) was never emitted for GEP resulting pointers. While such SPIR-V was (mostly) accepted by the NEO GPU driver, the generated SPIR-V was incorrect. The newly added test (pointers/getelementptr-bitcast-load.ll) verifies that a correct bitcast is added for more complex cases and passes spirv-val. The test is based on an OpenCL CTS test (basic/prefetch).
